Narrative:

Due to alternator failure, was trying to navigation in confined airspace without talking to ATC. Kissed south edge of eppley field class C airspace because of lack of ground reference -- then wandered into edge of offutt AFB class 'C' airspace while trying to locate the south omaha airport. I had flown over the airport and not seen it and did not realize I was in offutt space until I was over the noted antennas. Contributing factors: chart clutter in area and lack of specific references, 'I can do this' attitude, uncertainty about battery status. What I would do differently: communication with ATC and have their permission to operate in their airspace despite using battery power.

Narrative: DUE TO ALTERNATOR FAILURE, WAS TRYING TO NAV IN CONFINED AIRSPACE WITHOUT TALKING TO ATC. KISSED S EDGE OF EPPLEY FIELD CLASS C AIRSPACE BECAUSE OF LACK OF GND REF -- THEN WANDERED INTO EDGE OF OFFUTT AFB CLASS 'C' AIRSPACE WHILE TRYING TO LOCATE THE S OMAHA ARPT. I HAD FLOWN OVER THE ARPT AND NOT SEEN IT AND DID NOT REALIZE I WAS IN OFFUTT SPACE UNTIL I WAS OVER THE NOTED ANTENNAS. CONTRIBUTING FACTORS: CHART CLUTTER IN AREA AND LACK OF SPECIFIC REFS, 'I CAN DO THIS' ATTITUDE, UNCERTAINTY ABOUT BATTERY STATUS. WHAT I WOULD DO DIFFERENTLY: COM WITH ATC AND HAVE THEIR PERMISSION TO OPERATE IN THEIR AIRSPACE DESPITE USING BATTERY PWR.
